Umbrella Locust Tree

Umbrella Locust Tree

In the event that you noticed them, you’ll probably identify locust trees. They can be easily recognized by their ethereal foliage and leathery dried. They’re tall, powerful, fast growing deciduous shade trees indigenous to North America that increase from 40 to 70 feet. Locusts have a quickly spreading and powerful root system that’s a benefit in places needing erosion control. The umbrella locust tree (Robinia pseudoacacia “Umbraculifera”), also also referred to as umbrella black locust or umbrella typical locust, is a dwarf cultivar that grows to 20-feet tall. Umbrella locust trees are grown because of their umbrella -shaped canopy as decorative show specimens.

Growth Routines

The umbrella locust tree is a dwarf kind of tree that reaches 20 feet high. It’s an umbrella- shaped canopy, with 6- to 14-inch, green leaves that are dark and numerous leaflets on twigs. The trees are salt and drought tolerant, making them excellent trees for sea-side or dry locations. They’re hardy in U.S. Department of Agriculture zones 3 to 8. Umbrella locust trees create large, cream-coloured, aromatic clusters of pea like flowers that create 2 to 4 inch-long crimson, black seed pods, or brown.


Locust tree cultivars contain Tortuosa, Idaho, Purple Gown, and Frisia. Frisia grows up to 50-feet tall and has golden-yellow leaves. Idaho develops to 40-feet tall with flowers that are pink. Purple Gown develops to 40-feet tall and has bronze- red leaves which keep a few of the purplish hue through the entire season. Tortuosa is a little cultivar, only reaching 10-feet, with twisted branches and few to no flowers.

Pests and Diseases

Borer blown over and weakens the trunk of trees. Locust tree pests contain scales, locust leafminer, and the carpenter worm. Diseases that impact locust tree types contain powdery mildew, leaf spot, and canker.

Invasive Tendencies

When planted near normal places, trees favor soils with excellent drainage, but might pose a risk to indigenous vegetation. Although it’s a native tree, it’s to the federal listing of invasive species. They spread quickly through root suckers and seed droppings if left unchecked and untended, shading out other vegetation. The big, flowers that are fragrant take on other crops for pollination. Bark leaves and seeds are toxic if consumed.
